Open .Dmg File On Windows Zip Has Support

You open them, drag the app to your Applications folder, and then eject them, saving you the hassle of the dreaded Install Wizard of most Windows apps.

So if all they are is a folder for an app, why do we use them instead of just downloading the app itself.

DMG files include something called a checksum, which basically verifies that the file is 100 intact.

And thats second reason why macOS uses DMG files: theyre a compressed format (like a ZIP file ) that makes your download smaller.

All you really need to do is double-click the DMG file to open it and mount it to your Mac.

Some DMGslike the Steam DMG shown abovehave styled backgrounds, but this is only cosmetic.

It may take a second to copy over, but when its done, you can launch the app from Launchpad or Spotlight like you would any other app.

But, if you need to get one open, 7-Zip has support for extracting DMGs.

If you want to convert the DMG to a different compressed format (like ISO, which is much like the DMG file format for Windows), a tool like dmg2img will get the job done.

In the window that pops up, select the folder you want to encrypt and click the Choose button.

After typing the password, the DMG file will mount like any other.
